Full-Stack Python & AI Engineer
About Me
I'm a Full-Stack Engineer specializing in high-performance Python backends and LLM/AI integration for SaaS products. Over the past 3+ years, I've built and scaled systems serving 100,000+ active users, cut API latency by 40%, and shipped AI-powered features — intelligent search, recommendations, and support automation — into production at funded tech companies.
My engineering foundation covers the full stack: Python APIs (FastAPI, Django REST), React frontends, PostgreSQL and MongoDB databases, and AWS + Docker cloud deployments with CI/CD pipelines. I don't just write code — I deliver measurable business outcomes: faster systems, lower infrastructure costs, and features that users actually engage with.
I work remotely with international clients across the US, UK, and beyond. I communicate clearly in English, overlap with US/UK business hours, and handle payments via Wise, Payoneer, or PayPal with standard international contracts.
What I Bring to Every Engagement
Performance-first mindset
Every system I build is profiled, optimized, and ready for scale before it ships.
Real-world AI integration
I've shipped LLM features into live production systems — not just side projects.
Results you can measure
I track and report the business impact of my work: latency, uptime, conversion, cost.
Remote-native work ethic
Clear async communication, overlap with your timezone, and no hand-holding needed.
